Ok system sounds and things like XMMS have sound but no games. The first fix left libasound-dev broken, fixing it uninstalled a bout 5 -dev sound packages for things like SDL. How do I get them to reinstall?

I already did the same thing to the libasound2-dev as hubi suggested for libasound , so I have it reinstalled. IS there a list somewhere of packages that have been rmoved?
